  • SOUND REINFORCEMENTLOUDSPEAKER SYSTEMS

  • FREEDOM OF CHOICE

    Theres a little something for everyone

    in SR Series II. From small combo vocal

    reinforcement to large club systems, from

    mobile DJ and recorded music repro-

    duction to stage monitoring, front fills and

    main PA stacks in concert applications. SR

    Series II has evolved into being the first

    choice of musicians and sound engineers

    worldwide. Heres what this evolution has

    produced.

    MORE MODELS

    You have 13 total configurations from

    which to choose including two extremely

    versatile floor monitors, five 2-way and

    three 3-way full range stage speakers, and

    three powerful subwoofers. SR Series II

    gives you more.... more systems containing

    large format compression drivers and

    more component combinations. In short,

    more loudspeaker systems to fit a wide

    range of professional sound reinforcement

    requirements.

    This newest variation ofhorn technology delivers vertical coverage with theweve ever achieved in largesystems.

    Constant Directivity90 horizontal by 50lowest throat distortionformat high frequency

    Our newest horn technology, incor-

    porated in five SR Series II models, delivers

    90 horizontal by 50 vertical coverage.

    Optimized Aperture technology is the result

    of designing the compression driver and

    horn together thus providing optimum

    performance. The large format com-

    pression driver has a 38 mm (1 1/2 in)

    exit, eliminating the 50 mm (2 in)

    transition tube, and allowing the phase

    plug to couple directly to the waveguide for

    greatly reduced midband distortion. The

    result is pure and precise mid and high

    frequency reproduction even at the highest

    sound pressure levels.

    LARGE FORMAT

    COMPRESSION DRIVER

    OPTIMIZED APERTURE

    HORN/DRIVER

    Designed exclusively to match the new

    horn, the 2447J compression driver incor-

    porates the absolute latest in compression

    driver technology. Its design virtually

    eliminates the need for a tweeter by

    smoothly extending high frequency

    response to well above 18 kHz. The result

    is outstanding midrange performance with

    sparkling highs and crisp, clean vocals.

  • ADVANCED TRANSDUCER

    TECHNOLOGY

    The 2119H transducer was developed

    for extra output power capability in

    dedicated midrange applications. It is

    incorporated in the SR4735A. Our new

    2417H small format compression driver

    incorporates the lightest diaphragm we

    have ever made, resulting in exceptional

    transient response and enhanced high

    frequency clarity. In fact, the 2417H

    delivers 5 dB greater level at 15 kHz than

    its predecessor. It is used as a high

    frequency element in the SR4735A and

    SR4738A 3-way systems and the SR4722A

    2-way system.

    The 2447J employs our Coherent

    Wave phase plug to maintain absolute

    phase coherency and increase high

    frequency output. To reduce distortion,

    improve reliability and extend high freq-

    uency performance, the large diameter

    diaphragm incorporates a radial rib

    design and JBLs patented three-

    dimensional diamond pattern surround. A

    100 mm (4 in) diameter edgewound

    aluminum voice coil drives the large format

    diaphragm and a powerful 9 kg (20 lb)

    magnet structure delivers extremely high

    efficiency and superb transient response,

    thus producing superior acoustic output

    without sacrificing clarity and articulation.

    With improved high frequency

    performance and lower distortion, many

    applications previously requiring a 3-way

    system can now be handled well with a

    lower cost 2-way system.

  • CONNECTORS

    AND CROSSOVER

    NETWORKS

    The terminal cup is made of heavy

    gauge steel to endure years of road use and

    abuse. You can now choose between the

    ease and simplicity of l/4-inch phone

    jack(s) or the assurance of maximum

    current transfer and the ability to use a

    single connector for full range or biamp

    applications with the Neutrik Speakon

    connectors. For your convenience, both

    are included on the SR Series II except for

    the SR4732A-T which is intended for

    tri-amp use only and is equipped with dual

    8-pole Speakon connectors.

    A high-current, low-profile rotary

    switch selects between Passive (full range)

    and Biamp settings making changes in

    operational modes quick, easy and

    reliable.

    SR Series II crossover networks are

    manufactured with the highest quality

    close-tolerance capacitors, high-power

    resisters and low-loss inductors to assure

    the smoothest possible acoustic response.

    (See Network Facts, left)

    VGC low frequency transducers control beat bycreating an airflow around the voice coil providinggreater reliability, very low distortion and reducedpower compression.

    ROAD TESTED

    VGC tRANSDUCERS

    Finally, our VGC (Vented Gap

    Cooling) low frequency transducers,

    proven workhorses, are the foundation of

    most concert sound systems worldwide.

    Like the top tour sound engineers, you can

    expect the same unparalleled power

    handling, low distortion, extremely wide

    dynamic range and low power com-

    pression. From a users standpoint, this

    means more acoustic output for every

    amplifier watt of input, superior reliability

    and sonic quality second-to-none.

    NETWORK FACTS

    In most models, network PCB's are anchored to the bottom ofthe cabinet, allowing beat to dissipate upward. This andother design features provide additional structural integrityand improved reliability. SR Series II networks are engi-neered to survive many years of road work and heavy duty

    reducing heat generation and allowing more power to reachthe transducers. Polystyrene bypass capacitors are utilized in

    As transducer power ratings increase, so do the requirementsfor long term power handling in the crossover networks. Infull range systems, the passive crossover must also be engi-neered to handle the higher current levels while maintainingphase integrity and providing the smoothest possiblecomponent-to-component transitions.

    All resistors utilize a new 4-point mounting topology formechanical stability. Chokes feature very low insertion loss,

    critical circuit locations to improve the high frequencytransient response.

    cycle applications.

  • CABINET CONSTRUCTION

    SYSTEM FACTS

    SR Series II enclosures are fabricated

    of high grade, void-free plywood for maxi-

    mum structural integrity. All joinery is fit to

    exacting tolerances and bonded with high-

    temperature adhesives. During assembly,

    the entire enclosure is placed into a l0-ton

    press to assure that all bonded surfaces

    make contact and are held in place while

    the adhesives cure. Further strengthening

    and stiffening is achieved through the use

    of internal hardwood bracing. The result is

    an enclosure of unequaled strength,

    intended to endure the perils of road work

    for many years.

    The enclosure exterior is laminated

    with a proprietary fabric for excellent

    protection against scrapes and scratches

    providing a rich, attractive appearance.

    With the exception of the SR4719A

    Subwoofer System and the floor monitors,

    all SR Series II enclosures are trapezoidal

    in shape which permits tight grouping to

    form arced arrays when used in multiples.

    Of the trapezoidal models, all but one (the

    SR4722A) share the same footprint

    allowing the corner protectors to interlock

    when stacking, so you dont need to worry

    about the top box sliding off as a result of

    vibration.

    Whether youre a musician needing a

    sound reinforcement system, a mobile DJ

    looking for the ultimate playback system

    or a sound rental company looking for

    maximum performance and reliability,

    SR Series II meets and exceeds your needs.
